A technique and algorithms for early detection of the started attack and subsequent blocking of malicious traffic are proposed. The primary separation of mixed traffic into trustworthy and malicious traffic was carried out using cluster analysis. Classification of newly arrived requests was done using different classifiers with the help of received training samples and developed success criteria.
The paper proposes an original equivalent circuit of the multiwinding transformer based on the classical theory of transformers and the introduction of a new parameter — the mutual inductance on leakage fluxes. The results of the calculation of currents and losses in the windings of a powerful toroidal transformer on the base of the original equivalent circuit of the multiwinding transformer are confirmed...
The article is devoted to the modeling of multiarc welding in ESI SYSWELD. Functionality of the program allows modelling MMA, MIG, MAG welding processes, submerged arc welding, multi-pass and hybrid welding. However, there is no mathematical model for multiarc welding. The use of multi-pass welding does not reflect the physical essence of the multiarc welding, because the bead joints in multipass...
We have developed novel THz spectrometer based on Fabry-Perot interferometer. The novelty of the device is related to the metal-covered high-resistivity silicon mirrors. Also an original body of mathematics which allows broadband incident signal spectrum reconstruction was elaborated.
A computational model of explosive opening switches, in which the conductor is broken by a ribbed barrier or by dielectric jets, is presented. The setup and results of TIM-2D hydrodynamic simulations with elastoplasticity, magnetic diffusion and electric circuit effects are discussed. The numerical simulations were done in Lagrange variables on unstructured grids. The results of the MHD opening switch...
UHF low power rectifier is considered. Influence of nonlinear parts' VAC vs. rectifier parameters is investigated. Conversion efficiency increased 3...10 times by means of resonant tunneling diode using. Experimental verification of mathematical model is carried out.
In this paper, we propose a simple and efficient model to predict the timing impact of crosstalk in high-speed interconnects with impedance discontinuities. This model is based on the reflection and superposition principles. The results of the simple model are accurate to picoseconds or less, when compared to HSPICE simulations with 1~40mm interconnect length. The model can also be extended to deal...
